Antitumor and chemopreventive role of major phytochemicals against breast cancer development
We examined current knowledge of their bioavailability, safety and modulation of molecular mechanisms including their ability to induce apoptotic cell death, promote cell cycle arrest, and inhibit cellular proliferation in different breast cancer cell lines and in vivo models. This review emphasises the importance of these naturally occurring phytochemicals and their potential of becoming therapeutic options in the arsenal against breast cancer development provided further scientific and clinical validation.PMID:37646820 | DOI:10.1080/14786419.2023.2251167 (Source: Natural Product Research)

Phytochemical, antileishmanial, antifungal and cytotoxic profiles of < em > Thymelaea tartonraira < /em > (L.) All. extracts
Nat Prod Res. 2023 Aug 30:1-7. doi: 10.1080/14786419.2023.2252153. Online ahead of print.ABSTRACTExtracts from leaves and stems of Thymelaea tartonraira (L.) All. growing in Tunisia were characterised for the presence of flavonoids and phenolic acids by LC-ESI-MS analysis. Twelve flavonoids and ten phenolic acids were detected for the first time in the aerial parts of this plant species, the most abundant compounds being gallic acid, kaempferol, catechin, chlorogenic acid, naringenin and acacetin. The extracts were subjected to in vitro antileishmanial, antifungal and cytotoxic assays, showing promising antileishmanial act...

Nat Prod Res. 2023 Aug 30:1-10. doi: 10.1080/14786419.2023.2252154. Online ahead of print.ABSTRACTIn the present study, fresh whole corn plants along with half milk kernels line were treated with live and hydrolysed yeast with different concentrations before ensiling and kept in airtight bags and then into mini silos in order to achieve anaerobic conditions for proper fermentation. The buckets were opened after different time intervals to characterise the material, quick acidification, dry matter recovery, and aerobic stability of silage respectively. Moreover, mycoflora and aflatoxin contamination were also analysed. The ...

A comparative study on essential oils from the leaves and stems of Vietnamese < em > Mikania micrantha < /em > Kunth
In this study, the essential oils from leaves and stems of M. micrantha were extracted by hydrodistillation method, and the chemical profiles of essential oils were then analysed by gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC/MS). It was found that there were similarities and differences in chemical compositions and their percentage between the essential oils obtained from these two parts. The dominant components of leaves essential oil are β-Cubebene, Germacrene D, and α-Zingiberene, accounting for 11.34%, 10.96%, and 10.76%, respectively. Additionally, the major components of stems...

Simple two-step purification and characterisation of peroxidase from < em > Citrullus colocynthis < /em >
Nat Prod Res. 2023 Aug 25:1-10. doi: 10.1080/14786419.2023.2248644. Online ahead of print.ABSTRACTPeroxidase is a biotechnologically important enzyme. The purification of peroxidase from the root of Citrullus colocynthis was carried out in a simple two-step process with maximum purity level. The sample was extracted in a high salt buffer, and the enzyme was partially purified with a Q-Sepharose anion exchange column. Final purification was carried out with HighLoad 16/600 Superdex G-75 column. The purified protein was analysed with SDS gel electrophoresis, which suggested a single band of approximately 35 kDa. Further, the...
